2nd Arecibo Survey


The 2nd Arecibo Survey (ar2) published its results in 1982 and 1986 with a total of 6 new pulsars discovered. It detected a grand total of 18 pulsars. The fastest pulsar discovered was J1939+2134 with a period of 1.55781 milliseconds and the slowest pulsar was J1939+2449 with a period of 645.30247 milliseconds. The smallest pulsar dispersion measure was J1857+0943 with a DM of 13.2995 pc/cc and the largest pulsar dispersion measure was J1854+1050 with a DM of 207.2 pc/cc. There were a total of 326 pulsars known before the first discovery was published. This survey increased the total amount of known pulsars by 2.0%.

There were 3 papers written about the discoveries of this survey: A Millisecond pulsar, New millisecond pulsar in a binary system, Results of Two Surveys for Fast Pulsars.
